fifthly, finally screwing the high-strength bolts (10) of the ridges in sequence, and then completing the assembly of the cable penetrating type ridge cable dome (03) on the ground;

step four: a lifting cable (05) is installed in an upper hole of a node ear plate (63) of the nth ring of ridge rod node (6), the other end of the lifting cable is connected to a hoisting machine, a jacking jig frame (04) jacks a central tension ring (3) of a reeved ridge rod cable dome (03) step by step, meanwhile, the peripheral lifting cable (05) lifts the nth ring of ridge rod node (6) of the reeved ridge rod cable dome (03) until the reeved ridge rod cable dome (03) is lifted to the height of a double-hole ear plate (15) of a ring truss module unit (1), and at the moment, the nth ring of ridge rod node (6) of the reeved ridge rod cable dome (03) and the double-hole ear plate (15) of a modular assembly ring truss (02) are located at the same position;

step five: connecting an N-th circle ridge rod node (6) of the reeving ridge rod cable dome (03) with an upper hole of a double-hole ear plate (15) of the modular assembly ring truss (02) by using a high-strength bolt or a pin shaft;

step six: the connection between the N-th circle of inclined cables (7) and the node ear plate (63) of the N-th circle of ridge rod node (6) is dismantled, the N-th circle of inclined cables (7) are tensioned until the penetrating type ridge rod cable dome (03) reaches the designed elevation, and the N-th circle of inclined cables (7) are connected to the lower hole of the double-hole ear plate (15);

step seven: and (5) removing the lifting cable (05) and the jacking jig frame (04), and completing the construction and installation of the integral full-assembly cable-penetrating type ridge rod cable dome and the modular assembly ring truss structure system.

13. The construction method according to claim 12, wherein: the designed elevation is L/10.

14. The construction method according to claim 12, wherein: the prestress applied to the spinal cord (53) is 35% of the spinal cord breaking force.
